自定义移动 Facebook 登录按钮？

【问题描述】：

我成功地为网页定制了登录按钮，但我该如何为 ios 做呢？我一直在寻找，但没有找到任何东西。

我目前使用的是 Facebook SDK 3.0，它实现起来相当容易，但 FBLoginView 按钮的设计让人大跌眼镜。我正在尝试用一个动画按钮来掩盖它，并向前触摸它背后真正的 Facebook 按钮。

Apple 会在提交后拒绝这种解决方法吗？ 一定有更简单的方法，不是吗？

我猜这确实是重复的，它几乎完全相同并且有效！我应该将搜索重点放在 FBLoginView 上，我可能会找到我的答案。谢谢！

【参考方案2】：

是的，您可以使用以下代码进行更改。

    for (id obj in loginview.subviews)

    if ([obj isKindOfClass:[UIButton class]])
    
        UIButton * loginButton =  obj;
        [loginButton setBackgroundColor:[UIColor blueColor]];
        UIImage *loginImage = [UIImage imageNamed:@"facebook_btn~ipad.png"];
        [loginButton setBackgroundImage:loginImage forState:UIControlStateNormal];
        [loginButton setBackgroundImage:nil forState:UIControlStateSelected];
        [loginButton setBackgroundImage:nil forState:UIControlStateHighlighted];
        [loginButton sizeToFit];
    
    if ([obj isKindOfClass:[UILabel class]])
    
        UILabel * loginLabel =  obj;
        loginLabel.text = @"Login with facebook";
        loginLabel.textAlignment = NSTextAlignmentCenter;
        loginLabel.frame = CGRectMake(0, 30, 600, 30);
        //loginLabel.text. = [UIFont fontWithName:@"Default" size:30.0];
        [loginLabel setFont:[UIFont boldSystemFontOfSize:27]];
    

【参考方案3】：

请阅读 Facebook SDK 中的 README 文件。 您必须在 info.plist 中添加 Row - FacebookBundleName 并将其命名为您的捆绑包。 然后，使用此名称将包添加到您的项目中，并放入名为“lang.lproj”的文件夹中： 例如：en.lproj - it.lproj - fr.lproj - es.lproj.... 在这个文件夹中你必须添加 Localizable.strings 文件，然后你可以本地化很多短语，比如：

"FBLV:LogOutButton" = "Log Out";
"FBLV:LogInButton" = "Log In";
"FBLV:LoggedInAs" = "Logged in as: %@";
"FBLV:LoggedInUsingFacebook" = "Logged in using Facebook";
"FBLV:LogOutAction" = "Log Out";
"FBLV:CancelAction" = "Cancel";

希望对你有帮助！
